Most nsIEditActionListener::Will*() are not implemented, except
WillDeleteText() and WillDeleteSelection() which are implemented by
FinderHighlighter. So, we can get rid of the other Will*() from it.
This patch removes a lot of unnecessary virtual calls and copy of strong
pointers to edit action listeners of EditorBase.

Although nsIEditActionListener::WillInsertNode() nobody implements actually,
we should remove it in a follow up bug.
nsIEditActionListener::DidInsertNode() is implemented only by HTMLEditRules.
So, if we make it not use nsIEditActionListener, we can remove it too.
However, keep it for now.
On the other hand, they don't need to receive index of the insertion point.
WillInsertNode() needs next sibling of the insert point, but DidInsertNode()
needs nothing because listener can compute it with new inserted node.

nsIEditActionListner::DidSplitNode() takes 4 arguments, the right node,
old offset in the old right node before splitting, the new left node and
nsresult.
Computing offset for this doesn't make sense because it's always same as
the length of the left node. Additionally, nobody currently use nsersult.
So, we can get rid of it now.
Fortunately, nobody including comm-central and BlueGriffon implements
WillSplitNode(). So, we can get rid of it. However, removing interface
method should be done in a follow up bug. So, we can remove offset computation
in EditorBase::SplitNode() completely in the future.

nsIEditActionListener::WillCreateElement() and
nsIEditActionListener::DidCreateElement() are implemented only by m-c.
So, we can remove a set of container node and offset in it from their argument.
Instead, WillCreateElement() should take a node which will be next sibling of
the new node.
Note that only implementation of them is, HTMLEditRules::DidCreateElement().
So, we can get rid of them and can call HTMLEditRules::DidCreateElement()
directly from EditorBase::CreateNode(). However, such change should be done
in another bug which checks all nsIEditActionListener method implementations.
